In 2019, scientists at the Swiss Federal Institute of Technology Lausanne built a machine that allows fish and bees to talk to each other. The researchers created a robot translator that can send messages back and forth between a group of zebrafish and a swarm of honeybees. To really challenge themselves, the scientists decided to conduct their experiment from different countries. The fish were at one location Switzerland. The bees were miles away in neighboring Austria.
The robot translator issued commands to each species then translated their responses into signals for the other group. So the fish might be shown a color or tail movement, which influenced the direction of their swimming. This would then be translated into a vibration or a change in temperature, which caused the bees to move to a different area. The bees’ motion would then be translated into a signal for the fish, and so and so forth. To start with the experiment was absolute bedlam, but after 25 minutes of confusion the animals began to respond to their robotic stimuli.
Although this might sound like an absurd experiment, communicating with animals has many real world applications, like stopping birds from flying over airports or warning bees about pesticides on plants.
